摘    要:由于在工程图学中,用正投影法解决画法几何中的某些度量和定位问题往往很不方便。为了简化作图,本文介绍了直线辅助投射法及其在解决一些工程图学问题中的应用。该法具有作图简单、应用范围广的特点。

关 键 词:直线辅助投射法 余角辅助投射法 直角辅助投射法

Abstract:In engineering drawing, it is always inconvenient for orthographic projection to solve some measurement and orientation problems. In order to simplify drawing, this paper introduced a method of line secondary projection. It has been proved that the presented method is very simple and effective.
Keywords:Line secondary projection  Oblique secondary projection  Orthogonal secondary projection  Projection-line load
